Compare Technics EAH-AZ100 Earbuds vs Denon Perl Pro True Wireless Earbuds

ANC is broadly strong and often near flagship level, though several reviewers say it still falls short of the very best Bose-style silence.

ANC is generally usable to good, but it is not the product’s strongest feature; reviewers often note rivals perform better or consistency varies.

Android compatibility is praised for LDAC, fast pairing, and strong ANC value with Android phones.

Android compatibility is conditional: Snapdragon-compatible phones benefit most, while Samsung and Google users cannot access the highest-bitrate features.

The app is mostly praised for useful controls, customization, stability, and EQ access, despite some complaints about layout.

The app is feature-rich and important for setup and customization, but reviewers also reported crashing, slow loading, and some mandatory-app friction.

aptX support is a weakness because one reviewer specifically wished Qualcomm aptX codecs were included.

aptX support is valued, especially aptX Lossless, but reviewers warn that Snapdragon Sound compatibility remains niche.

Video sync is mostly strong, with two reviewers reporting zero or no visible lag, while one notes a slight delay with some codecs.

Audio-video sync was only directly evaluated by one reviewer, who reported no lag while watching YouTube on an iPhone.

Auracast support is a concern in one scored review because the reviewer criticizes its absence.

Bass is widely praised for depth, control, punch, and low distortion, with only one review criticizing the default balance as too boomy.

Bass is usually described as controlled, deep, and impactful, especially after personalization, but a few reviewers found default or customized bass either light or too boosted.

Battery life is consistently a strength, with reviewers praising long ANC runtime and major improvement over the AZ80.

Battery life is acceptable to good for ANC earbuds, but reviewers vary from respectable and impressive to merely typical or could be better.

Bluetooth reliability is consistently praised, with reviewers reporting stable connections and no meaningful dropouts.

Carry case quality is mixed: reviewers praised solid construction and magnet security, while others noted bulk, difficult bud removal, or a weak case feel.

Charging is viewed positively where evaluated, especially wireless charging and case convenience.

Charging is mixed: reviewers praised fast, wireless, and USB-C charging, but one reported the wireless-charged case getting extremely hot.

Codec support is praised for LDAC/LC3 breadth, but the absence of aptX is called a mild limitation.

Codec support is a strength for compatible devices, but reviewers also note limitations with AAC, Snapdragon compatibility, and missing LDAC.

Comfort trends positive thanks to smaller, lighter ergonomics, but fit fatigue and bulk remain concerns for some ears.

Long-use comfort is divisive: some reviewers found the earbuds comfortable, while others reported heat, rubbing, pressure, or discomfort from the large housings.

Design and aesthetics are generally praised as premium, sleek, compact, or classy, though a few reviewers find the look plain.

Design splits reviewers: some like the smart, elegant, distinctive look, while others strongly dislike the oversized dinner-plate appearance.

Eartip fit is generally good with the right size, but some reviewers report looseness, bulk, or falling out.

Eartip fit is highly personal: several reviewers achieved a secure, comfortable seal, while others experienced popping out or poor fit.

Ear tip options are considered useful and generous, especially for finding the right fit across ear sizes.

Ear tip size options are well received, with praise for multiple tips, foam options, and fit flexibility.

EQ customization is a clear strength, with many reviewers praising the eight-band control and meaningful tuning options.

EQ customization is useful and often praised, especially ProEQ and immersion controls, though one reviewer wanted more targeted frequency bands.

Find My support is useful for peace of mind, though one reviewer is disappointed by the location behavior.

Frequency response impressions are mixed: one review calls it strange, while others praise accuracy, balance, and low distortion.

Frequency balance is improved by firmware and personalization for some reviewers, but profile differences can make the tonal result uneven for others.

Included accessories draw criticism where reviewed because foam tips are missing despite multiple silicone tip sizes.

Included accessories are a positive because reviewers appreciated the supplied fit options, wings, and foam tips.

Instrument separation is a standout strength, with reviewers hearing layers, voices, and complex arrangements as distinct and clearly placed.

Instrument separation is a consistent positive, with reviewers hearing clean layering, distinct elements, and better separation after calibration.

The integrated microphone system is generally clear and usable, with reviewers praising voice clarity and detail for calls.

Independent left/right earbud use is praised as convenient and useful when scored.

Independent left/right bud use was praised in one review because either earbud could play alone while the other charged.

LDAC is received positively for higher-quality playback and better sound from compatible Android or hi-res sources.

LDAC is a weakness because multiple reviewers explicitly note that the earbuds do not support it or that LDAC competitors are easier for Android users.

Lossless audio support is appreciated and sounds crisp to some reviewers, but its benefit depends on compatible devices and is not always transformative.

Maximum-volume clarity is praised for staying clean and distortion-free even at high levels.

Maximum-volume clarity is a strong point, with reviewers praising clean output, crystal clarity, and low distortion even at high volume.

Microphone noise reduction is polarized: several reviewers praise wind and background suppression, while one reports failed clarity and cutouts.

Call quality is mixed, ranging from serviceable or excellent in some reviews to choppy, robotic, or poor in others.

Call microphone quality is generally good, with reviewers hearing clear calls and intelligible voice pickup, though not always perfect.

Midrange and vocals are generally described as clear, detailed, warm, and more forward than the previous model.

Midrange performance is generally strong, with reviewers praising clear vocals, layered mids, and presence; one reviewer found the default tuning too mid-forward and radio-like.

Multi-platform compatibility is praised because the app and customization work across iOS and Android.

Multi-platform compatibility was positively tested in one review through automatic switching between a tablet and phone.

Multipoint is a major strength, with reviewers repeatedly praising reliable switching and three-device connectivity.

Multipoint connectivity is one of the most consistently praised usability features, with reviewers describing seamless or perfect switching between devices.

Passive isolation is viewed positively when the tips seal well, with reviewers noting isolation even before ANC is active.

Passive isolation benefits from the seal, foam tips, and fit options, with reviewers describing a solid seal and better noise isolation.

Portability is strong because the case is repeatedly described as pocketable, small, and easy to carry.

Portability is mixed because some reviewers found the case pocketable, while others called the case bulky and the earbuds themselves large.

Preset EQ quality is mostly positive, especially Direct, Dynamic, and Treble+ modes, though SuperBass+ is too heavy for one reviewer.

Personalized profile quality is a defining strength: most reviewers found AAT or personalized sound dramatically better, though one reviewer disliked the profile result.

Smudge resistance was only directly assessed once, with the reviewer noting minimal fingerprints on the case.

Setup and software simplicity are mostly positive, but the lack of a physical pairing button adds friction for one reviewer.

Setup and software are mixed: the hearing test can impress and work well, but some reviewers found tinkering slow or less polished than rivals.

Soundstage depth and immersion are generally strong, with reviewers describing holographic space, a bubble of music, and studio-like presence.

Soundstage width receives strong praise, with reviewers describing the presentation as spacious, broad, expansive, and room-like.

Soundstage width earns broad praise, with multiple reviewers describing wide, open, spacious, or expansive presentation from earbuds.

Spatial audio is mixed: reviewers appreciate Dolby/head-tracking support, but several find it merely decent, distracting, or less clear than stereo.

Spatial audio is polarized, ranging from underwhelming in one review to immersive, excellent, and wide in several others.

Stability is mixed: several reviewers found the fit secure, while others would not trust it for vigorous movement.

Stability is generally good when the right tips or wings are used, with reviewers praising secure fit and reduced fall-out risk.

Touch controls are generally responsive and customizable, though sensitivity and personal preference create some mixed reactions.

Touch responsiveness is strongly rated, with reviewers describing responsive taps, reliable touchpads, and working commands.

Transparency mode is mixed: some find it natural or useful, while others hear hiss, over-processing, or weaker situational awareness.

Transparency or social mode is mixed: some reviewers found it gentle, useful, or convenient, while others called it basic, artificial, or ineffective.

Treble is usually considered clear, airy, detailed, and non-harsh, though one review says the default tuning lacks high-end content.

Treble is mostly clear and energetic, with praise for sparkle and highs, but some reviewers noted brightness, tame extension, tinny highs, or slight grain depending on profile.

Value is mixed-to-positive: reviewers like the premium feature set and sound, but several note the high price and strong competition.

Value depends heavily on price: reviewers criticized the original premium cost, but sale pricing and sound quality made it compelling for several.

Water and sweat resistance is adequate for workouts or rain, but one reviewer cautions against heavier rain exposure.

Water and sweat resistance is viewed as adequate for light workouts, sweat, and light rain, but no reviewer treated it as rugged waterproofing.

Weight comfort is praised because the earbuds feel better distributed, light, and easier to forget during use.

Weight and size comfort is a recurring concern because reviewers repeatedly describe the earbuds as large, awkward, or uncomfortable for smaller ears.
